Pismis 2: a poorly studied, intermediate-age open cluster.

DI FABRIZIO L., BRAGAGLIA A., TOSI M. and MARCONI G.

Abstract (from CDS):

We present CCD BVI photometry of the intermediate-age open cluster Pismis 2, covering from the brighter red giants to about 5mag below the main-sequence turn-off. The cluster is heavily reddened and is possibly affected by a differential reddening of ΔE(B-V)≃0.04-0.06.

Using the synthetic colour-magnitude diagram method, we estimate the distance modulus, (m-M)_0≃12.5-12.7, and age, τ≃1.1-1.2 Gyr, in a self-consistent way. The cluster probably contains a significant fraction of binary systems. The metallicity is most likely solar and the reddening E(B-V) ranges between 1.26 and 1.32 depending on the cluster region.
